In this paper, the authors' evaluation of the first self-build scheme for disadvantaged young people in Wales is set alongside evaluations of similar schemes set up in England in the 1980s and 1990s. Community self-build differs from traditional self-build where individuals, usually with skills and employment, build their houses for ownership. Community self-build is agency-initiated, builders are unskilled and usually working for state benefits and the finished houses belong to a housing association. The paper outlines how housing regulations, state benefits, (which are increasingly restrictive for young people), and training structures hinder community self-build projects. Moreover, community self-build schemes are usually set up in areas of social deprivation where the labour market is difficult, housing often residualised and the young people likely to be recruited are already alienated from education and training. Such innovative schemes often find themselves hindered by bureaucratic structures but they cannot work outside the law or in the informal economy. 相似文献

The NFPA 59A Standard and the Federal Regulation, 49 CFR Part 193, stipulate a level of 5 kW/m(2) as the criterion for determining the hazard distance to people exposure from a LNG fire. Another regulation (24CFR, Section 51.204) while stipulating a lower exposure limit of 1.42 kW/m(2) provides administrative relief from the regulation if mitigation measures are provided. Several countries in Europe and the Far East have adopted both a specified heat flux value (generally, 5 kW/m(2)) as well as modified dose criteria for human exposure hazard calculation in risk assessments. In some cases, the regulations in Europe require the use of lower values for children and physically challenged persons. This paper reviews the available literature on the phenomenon of skin burn caused by radiant heat exposure. The associated thermal and spectral properties of human skin are reviewed. The basis for regulatory setting, of 5 kW/m(2) and other exposure criteria (as a part of hazard and risk calculations) for evaluating distances to hazards from the exposure of people to radiant heat effects of large fires, is evaluated. An example calculation is provided to show the extent of reduction in the hazard distance to specified radiant heat flux from a fire when the spectral reflection and absorption properties of skin are considered with and without the inclusion of the mitigating effects of clothing. The results indicate that hazard distances calculated including the reflective and band absorptive properties (in IR wavelength) of skin results in a reduction of between 30 and 50% in the hazard distances obtained with current methodology, which ignores these effects. Unfortunately, there are no test results, from full-scale human-exposure-to-IR radiation, with which these predictions can be compared. 相似文献

城市中心区是核心服务职能空间的聚集区,根据服务职能空间在中心区范围内的离散程度,可将城市聚集模式分为高度聚集、适度聚集和均匀聚集三种。研究利用洛伦兹离散曲线分析上海人民广场中心区职能空间分布问题,得知其在职能支网结构的进阶力、服务职能的市场竞争力和局部地段的聚集引力的驱动下,其服务功能区主要以围绕聚集的匀散发展模式、匀散间的共生发展模式和匀散条件下的聚集配套模式分布和发展。这一推导过程及其研究结果为中心区服务职能空间的规划提供了科学理论,从而推动了中心区的升级和转型。 相似文献

The mid-20th-century communist ideal was for cities that were ‘of the people, by the people and for the people’. Wang Jun , an editor at Outlook Weekly magazine and author of a best-selling book on the planning of Beijing, describes how the ambition to accommodate public life in urban space is a relatively modern phenomenon that goes against the grain of a long tradition of landownership in China. Given this background, can the original notion of the ‘People's City’ ultimately survive the current wave of property privatisation? Copyright © 2008 John Wiley & Sons, Ltd. 相似文献

图瓦人属北疆古老游牧民族之一,跨境生活以及小族群的属性使得对他们的研究和调查有十分重要的政治、文化意义。基于传统聚落景观基因图谱的相关研究,选取我国三个保存相对完好的图瓦人草原聚落为研究对象,系统建构了“空间”“地缘”“文化”三大聚落景观基因系统并对其进行多尺度识别、配对、解译,分析目前聚落中的基因异变现象,对异变基因进行修复、改善。旨在梳理完善当前传统民居景观基因谱系划分的理论和方法,丰富我国的传统聚落基因库,并为游牧民族草原聚落基因信息链修复及景观基因区域识别提供可靠辩解的图谱借鉴依据,为保护和发展牧民定居聚落提供科学依据。 相似文献

针对智能视频监控领域的人数统计问题,该文提出了一种基于归一化前景和角点信息的复杂场景人数统计方法。首先在提取的前景二值图基础上,计算透视校正后的归一化前景面积。然后在提取前景区域有效角点信息的基础上,计算能够反映人群遮挡程度的遮挡因子。最后,将上述两种特征输入后向传播(BP)网络完成人数统计算法的训练与测试。实验表明,该方法可以有效地实现对复杂场景的人数统计。 相似文献
